β€œWhere precision meets performance β€” enabling smarter, safer, and more connected mobility.”

Introduction

In a world characterized by increasing urbanization, growing traffic congestion, and a heightened focus on security and law enforcement, efficient and automated systems for vehicle license plate detection and recognition have become paramount. The ability to swiftly and accurately identify license plates on moving or stationary vehicles has significant implications for applications such as traffic management, parking systems, security surveillance, and criminal investigations.

This project represents a pioneering effort in the field of computer vision, advancing the state-of-the-art in license plate detection and recognition. Leveraging the power of YOLOv8 (You Only Look Once, version 8) for object detection and EasyOCR for optical character recognition, this system demonstrates a holistic approach to converting raw video feeds into structured, actionable intelligence. It is not merely an algorithmic achievement but a seamless fusion of AI technologies designed for speed, precision, and scalability.

License Plate Recognition (LPR), often referred to as Automatic License Plate Recognition (ALPR) or Automatic Number Plate Recognition (ANPR), has long been an active area of research. Earlier systems relied on rule-based or template-matching methods β€” approaches that struggled with variations in lighting, plate format, and orientation. Moreover, these methods were computationally heavy and lacked adaptability to real-world data diversity.

The arrival of deep learning transformed computer vision entirely. Among its breakthroughs, YOLO (You Only Look Once) emerged as a revolutionary real-time object detection framework. Its latest iteration, YOLOv8, extends this legacy with unmatched accuracy and speed β€” ideal for dynamic vehicle recognition scenarios. However, detection is only half the equation; recognizing the alphanumeric content within plates demands the precision of OCR.

This is where EasyOCR excels β€” an open-source, deep-learning-powered library designed for efficient text extraction from images. When integrated with YOLOv8, it enables an end-to-end system capable of detecting, reading, and interpreting license plates in real-time. Together, these technologies propel VLPRS to the frontier of intelligent mobility analytics, redefining what’s possible in modern traffic automation and security ecosystems.

Object Detection with YOLOv8

Object detection is a critical task in computer vision, with applications ranging from autonomous vehicles to surveillance systems. Among various detection frameworks, YOLOv8 stands out for its real-time performance, high accuracy, and efficiency.

The core concept of YOLO (You Only Look Once) is to streamline detection using a single neural network that predicts both bounding boxes and class probabilities simultaneously. Each input image is divided into a grid, with each cell predicting objects in its region. This unified architecture enables real-time detection.

YOLOv8 introduces several enhancements over its predecessors:

  • Anchor Clustering: Determines optimal bounding boxes for objects of varying sizes, improving detection accuracy.
  • Object Detection & Segmentation: Combines detection with segmentation, enabling precise boundary identification.
  • Panoptic Feature Pyramid Networks (PFPN): Extracts multi-scale features to enhance performance on diverse object sizes and distances.
  • Speed and Accuracy: Achieves a balance between real-time performance and high precision, suitable for practical applications.

Its versatility allows YOLOv8 to be applied across multiple domains, including:

  • Autonomous Vehicles: Detects pedestrians, vehicles, and traffic signs.
  • Surveillance Systems: Identifies and tracks objects and individuals for enhanced security.
  • Retail & Inventory: Facilitates stock monitoring and loss prevention.
  • Agriculture: Supports crop monitoring, pest detection, and yield estimation.
  • Medical Imaging: Detects anomalies in X-rays or MRI scans.

In this project, YOLOv8 is integrated for vehicle license plate detection. Its real-time detection capabilities, precise bounding boxes, and adaptability make it an ideal backbone for license plate recognition when combined with OCR.

Implementation of ALPR

Automatic License Plate Recognition (ALPR) in this project builds on the YOLOv8-based license plate detection framework. It extends the system’s capabilities beyond mere detectionβ€”enabling the recognition and extraction of alphanumeric characters on license plates. By integrating Optical Character Recognition (OCR) technology, i convert license plate regions into machine-readable text for use in automation, surveillance, and analytics systems.

Core Workflow

  • Use YOLOv8 to detect license plates within vehicle bounding boxes.
  • Crop detected regions and preprocess them for OCR (contrast enhancement, resizing, denoising).
  • Apply OCR (EasyOCR / Tesseract) to recognize characters.
  • Format and validate recognized text according to license plate standards.
  • Output recognized numbers with confidence scores for tracking and analysis.
ALPR Process Flow

Once implemented, ALPR can identify vehicles in real time, extract their registration numbers, and provide data for applications such as traffic monitoring, parking automation, and law enforcement. This integration transforms YOLOv8 detection into a complete recognition system capable of analytical insight and operational control.

β€œCombining YOLOv8 detection with OCR-based ALPR creates a unified vision system capable of understanding what it sees.”

πŸ“œ Description of add_missing_data.py Script

The add_missing_data.py script plays a crucial role in ensuring data continuity by interpolating missing frames in the dataset. It applies linear interpolation techniques to reconstruct bounding boxes and attributes for frames that were missing or corrupted. This results in a more complete dataset, improving the performance of video-based license plate detection and recognition models.

  1. The script begins by importing the necessary libraries, including csv, numpy, and scipy.interpolate for data processing and interpolation.
  2. The interpolate_bounding_boxes() function is defined to handle the interpolation of missing bounding boxes in the data.
  3. The function extracts the required columns from the input data, including frame numbers, car IDs, car bounding boxes, and license plate bounding boxes.
  4. The script then iterates through the unique car IDs to process each car’s data separately.
  5. It calculates and interpolates missing frames between existing frames, ensuring a continuous sequence of frames.
  6. For each interpolated frame, a new data row is constructed with interpolated bounding boxes, and any missing data fields are set to β€˜0’.
  7. If the frame is part of the original data, the script retrieves data from the input data to complete the interpolated row.
  8. The updated interpolated data is collected in the interpolated_data list.
  9. Finally, the script writes the interpolated data to a new CSV file named test_interpolated.csv, ensuring that the header row matches the original format.

This script effectively addresses the issue of missing frames by performing linear interpolation, resulting in a smoother and more complete dataset for model training and evaluation.

  5. Frame-by-Frame Processing: Iterates through each frame:
    • Draws bounding boxes for cars and plates.
    • Displays license plate text and crops.
    • Writes each processed frame to the output video.
  6. Video Output: The final annotated video is saved with all visual overlays.
  7. Clean-Up: Releases both input (cap) and output (out) video resources to prevent memory leaks.
